SURF BOARD.

Application filed August 10, 1925. Serial No. 49,410.

This invention relates to improvements in surf boards. 1

The principal Ob]6CiJ of this 111V 3I1tl0I11S to provide a surf board. which is light in weight and therefore easily transported.

Another object is to produce a device of this character which takes up a minimum amount of space.

A further object is to produce a device,

of this character which will support a per? son when in the water, one which will not capsize and one which ma 7 be readily propelled through the water. I

A still further object is to provide means whereby a minimum amount of effort will cause a rapid propulsion.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure I is a side elevation of my 11nproved surf board,

Figure II is a top plan View of F igure I,

Figure III is a cross-section taken on the line 3-3 of Figure I, and

Figure IV is an enlarged fragmentary detail view of one of the propellers.

Applicant is aware of the fact that surf boards have been heretofore employed, both as life savers and amusement devices. These, however, have employed the common type of rotary propeller which necessitated a circular motion of the feet or arms in order to rotate the propeller. The result of this construction was that a large amount of head resistance materially cut down the speed at which the device could be propelled. Applicant has overcome this d lficulty by providing a very simple propelling mechanism which has a minimum amount of resistance when moving forward through the water and a large amount of resistance when moving backward thereby driving the surf board forwardly.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numerals 5 and 6 designate parallel angleiron frame members which are connected at their forward and rear ends by circular plates 7 and 8. At 9 I have shown a rest adapted or skid which serves to protect the propellers when the device 1s being takenashore.

Positioned on the angle-iron members, 5

and 6 is a rear float 11 and a front float 12, while positioned between the same is a board 13 having a seat board 16. c I I An upstanding member 17 is so positioned as to form a back, while upon the seat 14 is formed a stop. I'Vhen lying down upon the breast board 16,-the legs of the user will lie parallel with the float 11, while the hands Wlll grasp handles 18 and 19 which are attached to sliders 21 and 22, respectively. As both the sliders and their propelling surfaces are identicahbut By referring to FiguresIII and IV it will be noted that the slider 22 has a pair of yokes 23 and 24 attached thereto, which are adapted to straddle a slide-way 26 to be attached to the angle iron member 6. A similar slide-way is shown at g7 and is attached to the angle iron mem- Depending downwardly from the slider 22 is a strap 28 to which is pivo-tally secured P parallel members 29 and 31 as shown at 30.

between which are positioned hinges 32, 33

and 34 to which hinges are secured propelling plates 36, 37 and 38, respectively.

Theoperation of 'my device is as fol lows v Assuming that the same is complete as shown in Figure I, the user places the same in thewater with the result that the device will rest lightly upon the surface of the water. The user then straddles the device, preferably lying upon the breast board in such a manner that the member 17 acts as a stop, while the feet lie parallel with the float 11 and the chin rests upon the forward por tion of the breast board. Assuming that the parallel members 29 and 31 are in the folded position shown in Figure IV, the same are then bent downwardly to the position shown in Figure I after which the user grasps the handles 18 and 19 and by moving the arms backward and forwardso as to reciprocate the slider 22, motion will be imparted to the propellers. The forward movement of the arms will cause the propelling plates to assume the dotted line position of Figure I, while backward movement of the arms will portion 1-1 and a breast one will be described;

cause the plates to assume the full line position of Figure I, the result being that practically no resistance is ollered t the forward increment. of the propelling device, but considerable resistance is atl erded tothe backward movement 01" the same.

This action naturally VCRISQS the device as a whole, together with the user, to move forward through the water.

It will thus be seen that I have produced a very simple and etti'cient device and one which will accomplish all the objects above set forthuj 4 It is' obyieus that the'tloats-niay be made in any fanciful-design desired to" represent fish,-ani1nals 'or any other object desired.

It is to be understood that t lietorm bfllly invention herewith shown and described is to be taken as a preferred exalnpleot the seine; and that varie'us chan s 'i1rthe shape, size and ari'angeinenlib't parts maybe resorted to without departing trOin t-he spirit of the invent-ion or the scope of the subjoined claim.

Having thus described my invention, I claim':

In a device of the character described, a frame, a pair 0i floats securedtn said frame and separatedene from the other, a body supperting surface positioned between said floats, a slide-way formed on the opposite side'ofsaid frame' a carrier adapted to be reciprocated on said slide-Way, downwardly extending parallel members piwotally' secured to said carrier, and propellinguplates pivotally' secured to said downwardly extendingj parallelmeinber, said plates being adapted to lie in horizontalplane when said carrier is inove'd'torward andztodie in a vertical plane when: said' carrier is moved in a reverse direction. I

In testiindny whereof I a-l'tieti my signature.
